Description
[0001] The invention concerns a fitting in accordance with the
introductory clause of claim 1. Fittings of this type are used
especially for mounting and/or lockably installing a glass element
on at least one adjacent glass element, such that the glass
elements may be rigidly or flexibly attached to one another.
[0002] The catalogue "DORMA Glass Fitting Technology, Edition
September 1998" contains fittings of this type both with and
without integrated locks or built-in handles. Each fitting consists
of two fitting halves. Each fitting half is modularly constructed
and consists essentially of a substructure, which is formed from a
base and a functional insert, in which, e.g., the actual lock
and/or a latch mechanism is integrated, and a cover that fits over
the substructure. This provides various possibilities for joining
both indoor and outdoor all-glass elements.
[0003] The dihedral angle of glass elements that are flexibly
mounted on each other is limited by, among other factors, the shape
of the fittings, their covers, and their handles. The angular shape
of the previously known covers is a disadvantage in this respect,
because their edges meet too soon and restrict the dihedral angle.
Due to the formation of the edges, the covers require expensive
manufacture and are less than optimum from the standpoint of the
economical use of material. Furthermore, the cover can result in
personal injury, especially during cleaning work.
[0004] Attachment of the covers by clips or catches is
disadvantageous. Even during the initial installation, the catches
can be damaged or broken off. Especially after repeated disassembly
or assembly, tight seating of the cover is no longer guaranteed. In
the event of excessive stress on the element, especially in the
case of movable door elements, shaking and vibration can adversely
affect the catch.
[0005] The goal of the invention is to develop a fitting in
accordance with the introductory clause of claim 1, which forms a
compact and visually pleasing unit with the smallest possible
overall height and lateral extent, while retaining the previous
multiplicity of use and variety of functions. In particular, it
must be possible to attach the cover of the fittings securely on
the substructure beneath it.
[0006] This goal is achieved by the features specified in claim 1.
Advantageous modifications of the object of claim 1 are specified
in the secondary claims.
[0007] The fittings of the invention in accordance with claim 1 and
claim 2 have the advantage that a small overall height and compact
unit can be realized as a result of the elongated cover's convex
outer form, which extends in one arrow direction. The angular outer
form is avoided. Accordingly, the substructure located beneath the
cover is rounded, at least at the comers, so that a flat support of
the cover is formed. The curvature thus allows optimum utilization
of the structural space and optimization of the manufacturing
expense and the material that is used.
[0008] Although the material requirement for the cover of the
invention is extremely small, the stability properties and
functional properties are guaranteed. In particular, the at least
partially flat support of the cover on the substructure damps
vibrations caused by use and thus prevents unwanted loosening of
the cover.
[0009] The resulting outer contours have a visually pleasing design
due to the flowing and seamless transitions. All edges and borders
are provided with radii. The result is a universal,
model-independent, but general, outer design line. All material
thicknesses are reduced to a minimum. The flowing curve of the
outer contours, especially of the front surface, significantly
reduces the use of material and reduces, for example, manufacturing
problems related to casting practice. Metallic materials, plastics,
or so-called hybrid materials are conceivable. The color design is
practically unlimited. The specified properties also contribute
significantly to a reduction in production costs.
[0010] The covered arrangement of the substructure prevents
inadvertent manipulations and function-inhibiting contamination and
creates an advantageous visual appearance, including the aspect of
transparency of the glass elements. Furthermore, there are no
projecting parts, so that the cleaning of the glass surfaces is
also facilitated.
[0011] The fitting can be used both for rigid attachment of a glass
element, e.g., to a stationary glass element, and for flexible
attachment to adjacent glass elements. The interacting fittings are
designed to complement each other in such a way that they visually
constitute a unit.
[0012] In the case of supporting a movable glass element on the
upper side and the lower side, the fitting attached to the
stationary glass element is preferably angularly designed for
reasons of stability and in this way can simultaneously rigidly
join a transom window and a side part with each other. The fitting
attached to the movable glass element is rectangularly designed, so
that the overall view is of a rectangular unit. The glass elements
flexibly joined to each other by the fittings can be opened to a
dihedral angle of almost 180.degree. due to the advantageous shape
of the cover.
[0013] Furthermore, a lock can be integrated in the fitting. The
lock fitting is used for doors that are supported on a stationary
side part or transom window made of glass and, depending on the
design, can be installed on the upper side or lower side as a
so-called corner lock fitting or as a normal centrally arranged
lock fitting. The outer form of the fitting, i.e., the curvature of
the front surface, continues in the opposing fitting. The
functional insert contains at least the key-operated lock and
possibly the devices for integration of a door latch. In the case
of a nonglass frame, coordination with the frame structure is
necessary only with respect to satisfactory function between the
moving elements (latch, lock) in the lock fitting of the invention
and the corresponding openings of the locking plate on the frame
side. The interacting fittings are designed to complement each
other in such a way that they visually constitute a unit.
[0014] In a preferred embodiment, a handle is integrated in the
lock fitting, such that the lock fitting and the handle form a
general outer design line that matches in an esthetic and visual
sense.
[0015] The handle has the advantage that a reduction of the spatial
extent is realized by the grip, which is curved in the direction of
a hinged element, e.g., a door. A projecting free end of the grip
is avoided. The curvature thus allows optimum utilization of the
structural space and optimization of the manufacturing expense and
the material that is used.
[0016] The user is given a definite sense of grip. Due to an
inwardly bent or curved design of the grip, a haptically
advantageous tactile surface is created, which gives the user a
definite sense of grip and, especially when the user has an
incomplete grasp of the grip, prevents the hand from slipping.
Furthermore, the danger of catching articles of clothing or other
objects on the grip is minimized, since the distance between the
free end and the swiveling element is extremely small.
[0017] The handle consists of a grip, to which a connecting element
is attached at one end to form a single piece. The connecting
element serves the purpose of nonpositive connection with, for
example, a door. The grip and the connecting element have a round
cross section. The diameter of the connecting element preferably
increases in the direction of the swiveling element. On the one
hand, this minimizes the use of material, and, on the other hand,
it ensures stable mounting of a latch pin, which mechanically
connects the handle with a locking mechanism and an opposing
handle.
[0018] The free end of the grip is bounded by an inclined,
preferably flat, front surface, whose region facing the swiveling
element is preferably farther from the connecting element than its
region facing away from the swiveling element. The transitions
between the front surface and the grip have radii or bevels.
[0019] The handle is advantageously manufactured in a casting
process as a single piece and then finished. The flowing curve of
the outer contours reduces, for example, manufacturing problems
related to casting practice.
[0020] The handle and its individual parts can be manufactured from
various materials, such as brass, iron, high-grade steel, aluminum,
or bronze, or from other nonmetallic materials, such as
plastic.
[0021] Handles in accordance with the invention may be used as door
grips, window grips, or other types of grips, which are used purely
as handles or may have functions relevant to locking. Uses that are
relevant to locking, e.g., door or window grips, are realized
principally by a handle that is operated by turning, such that the
handle is coupled with the locking mechanism of the door or
window.
[0022] A fitting of the invention in accordance with claim 12 has
the advantage that the attachment of the cover involves no catches
or clips, which are susceptible to wear and may fail, e.g., as a
result of material fatigue. The realization of a partially
spring-loaded mounting also makes it possible to compensate for
use-related shaking or vibrations; greater tolerance compensation
of the components that are used also presents no problems.
[0023] In its inside chamber for holding the substructure of the
fitting, the cover has openings on one side, which interact at
least by frictional resistance with locking elements preassembled
in the substructure, so that the two complementarily engage each
other. For the final mounting of the cover, grooves are engaged
with pins that are spring-mounted in the substructure. The locking
elements may be designed, e.g., as slotted pins, which are driven
into bores in the substructure. In another embodiment, the locking
elements are designed as so-called grub screws, which can be
screwed into tapped holes.
[0024] To install the locking elements, either a striking tool or a
screwdriver is needed, depending on the design. The locking
elements are either formed on the substructure as a single piece
during manufacture or are preinstalled in the substructure directly
on site before the fitting is mounted. This also ensures that the
relatively small components are not lost. The locking elements form
a blockade in the openings against horizontal loads, so that it is
not possible for the cover to swing out. In the event that
disassembly becomes necessary, the cover is pushed as far as
possible in the spring-relieving vertical direction, so that the
grooves and pins can then be disengaged under a slight tensile load
by swinging away the cover. On the opposite side, the connection
between the openings and the locking elements can then be broken by
simple vertical movement of the cover. No tools are needed either
for assembly or disassembly of the cover. In this way, damage to
the often sensitive surfaces of the covers and plate-shaped
elements is prevented.
[0025] The externally invisible connection between the
spring-supported pins and the grooves is preferably arranged on the
side of the fitting facing the viewer, while the locking
connections are arranged on the side of the fitting turned away
from the viewer.

[0052] Components that are the same or have the same function are
labeled with the same reference numbers in the following
description; in particular, mirror-symmetrical components are
identically labeled.
[0053] Each of the fittings 1 shown schematically in FIGS. 1 to 8
consists of mirror-symmetrical fitting halves 2 and 3, such that
each fitting half 2 and 3 has a substructure 42 and a cover 4
mounted on it. The substructure 42 may be composed of a base 43 and
a functional insert 44.
[0054] Fittings 1 of this type are used, e.g., for the rigid or
flexible connection of glass elements in all-glass units. The glass
elements have bores or openings to allow mounting of the bases 43
on both sides, preferably by clamping with screws, possibly with
the intermediate insertion of a glass protector. Functional inserts
44 are then mounted on these bases 43. The functional inserts 44
may allow, for example, flexible support or rigid mounting of an
adjacent glass element. This modular construction of the fitting
system allows interchangeable use of bases 43, functional inserts
44, and covers 4. The glass elements may be designed, e.g., with
specific colors or profiles.
[0055] The more detailed explanation and representation of the
embodiments are limited below to the immediate region of the
fittings 1. The substructure 42 and its base 43 and functional
insert 44 are not shown, since each of them is located completely
and invisibly below the respective cover 4. All of the functional
elements are thus also advantageously covered, so that they are not
visible.
[0056] FIGS. 1 and 2 show a first embodiment of a fitting 1 in
accordance with the invention. Its fitting halves 2 and 3 and their
covers 4 are shown in the installed state in a view towards the
edge (not shown) of a glass element. Due to the mirror symmetry of
the fitting halves 2 and 3, the following description applies to
both fitting halves 2 and 3. Each cover 4 has two horizontally
oriented lateral faces 5 and 6, between which a front face 7
extends from one vertical edge 8 to an opposite vertical edge 9.
The cover 4 has a rectangular, elongated outer shape. The front
face 7 has an outwardly directed convex curvature, which increases
starting from the edge 9 shown on the right side of the drawing to
the left edge 8. The right edge 9 has an angularly projecting
lateral face 10, which spans a vertical edge of the glass element.
This lateral face 10 is also shaped outwardly convex. At the left
edge 8, the front face 7 tapers to an apex due to the greater
curvature, so that a direct glass support is formed there. The
lateral face 5 is partially formed on the glass edge with
extensions 11 and 12, which cover the glass edge. Between the
extensions 11 and 12, there is a recess 13, through which the
elements connecting the functional inserts, e.g., in the form of a
bearing pin, are connected.
[0057] FIGS. 3 and 4 show a modified embodiment of FIGS. 1 and 2,
in which a shortened lateral face 10 is formed on the vertical
glass edge. FIGS. 5 and 6 show another embodiment, in which no
extensions are formed on the lateral face 5. The lateral face 5 has
a recess 14, so that functional inserts can interact.
[0058] FIGS. 7 and 8 show another embodiment, which is suitable for
a fitting 1, which rigidly connects a transom window and a side
part and on which another glass element is flexibly supported. The
components essentially correspond to those of the embodiments
described above. Each fitting half 2 and 3 is additionally designed
with an angled projection 15 for the stationary connection of the
side part. The front face 7 is uniformly curved from one edge 8 to
the opposite edge 9 and tapers to an apex at both ends directly on
the surface of the glass. The lateral face 5 is likewise provided
with extensions 11 and 12 and a recess 13.
[0059] Each of the lock fittings 21 shown schematically in FIGS. 9
to 16 consists of fitting halves 22 and 23, each of which has a
substructure 42 and a cover 25 mounted on it. The substructure 42
consists of a base 43 and a functional insert 44.
[0060] Lock fittings 21 of this type are used, e.g., for glass
elements used as doors. The glass elements are supported on a
stationary glass side part or transom window. The more detailed
explanation of the embodiments is always limited to one fitting
half, due to the functional similarity.
[0061] FIGS. 9 and 10 show a first design of the lock fitting 21 as
a so-called comer fitting, such that the lock fitting 21 is mounted
at the upper and/or lower comer on the swiveling side of a glass
element, which is not shown in the drawings. In this case, the
glass element is designed to have a push grip in the middle of the
door and is locked relative to the surrounding field by locks
located in the corner fittings. The covers 25 of this lock fitting
21 are shown in the installed state in a view towards the edge (not
shown) of a glass element. The covers are positioned opposite each
other with mirror symmetry, and each has a rectangular,
horizontally elongated outer shape. Each cover 25 has two
horizontally oriented lateral faces 28 and 29, between which a
front face 30 extends from one edge 31 to the other edge 32. The
front face 30 has an outwardly directed convex curvature, which
increases starting from the edge 31 shown on the right side of the
drawing to the left edge 32. The right edge 31 has an angularly
projecting lateral face 33, which spans the vertical edge of the
glass element. At the left edge 32, the front face 30 tapers to an
apex due to the greater curvature, so that a direct glass support
is formed there. The lateral face 28 is partially formed on the
glass edge with extensions 34, 35, 36, so that the glass edge is
covered by them. Between the extensions 34, 35, 36, there are
recesses 37, 38, through which the elements located in the
functional inserts, e.g., in the form of a locking bolt, can be
passed. The front face 30 of the cover 25 has a projection 39, by
which the lock (not shown) is covered.
[0062] FIGS. 11 and 12 show a modified embodiment of FIGS. 21 and
22, so that the lock fitting 21 can also be used in the middle of a
door. Therefore, no extensions are formed on the lateral faces 28
and 29. The locking bolt is locked horizontally here.
[0063] FIGS. 13 and 14 show a design of the lock fitting 21 of the
invention as a center fitting, such that the lock fitting 21 is
mounted preferably in the middle on the swiveling side of a glass
element. In this case, the lock fitting 21 can have a door latch,
which is not shown in the drawings, with a latch and a lock with a
bolt, which work together with corresponding fittings of a locking
plate (not shown). The covers 25 of this lock fitting 21 are shown
in the installed state in a view towards the vertical edge (not
shown) of a glass element. Each of the covers 25 has a rectangular,
vertically elongated outer shape. Each cover 25 has two vertically
oriented lateral faces 28 and 29, between which a front face 30
extends from one horizontal edge 31 to the opposite horizontal edge
32. The front face 30 has an outwardly directed convex curvature,
which increases starting from the edge 31 at the bottom of the
drawing to the upper edge 32. The lower edge 31 has an angularly
projecting lateral face 33, which rests on the surface of the glass
element. At the upper edge 32, the front face 30 tapers to an apex
due to the greater curvature, so that a direct glass support is
formed there. The lateral face 29 contains recesses 37 and 38,
through which the elements located in the functional inserts, e.g.,
in the form of a latch and a locking bolt, can be passed. In the
front face 30, there are openings 40 and 41, through which the lock
can be operated by a door latch. The opposing half 23 of the
fitting has the same shape but is considerably flatter in
design.
[0064] FIGS. 15 and 16 show a design of the lock fitting 21 of the
invention as a center fitting with horizontal orientation, such
that the lock fitting 21 is mounted preferably in the middle on the
swiveling side of a glass element. In this case, the lock fitting
21 has a door latch with a latch and a lock with a bolt, which work
together with corresponding holding fixtures of an opposing fitting
installed in a side part. The fitting halves 26 and 27 of the
opposing fitting 24 are also shown and produce an ergonomic unit in
continuation of the curved shape of the fitting halves 22 and 23 of
the lock fitting 21. The covers 25 lie opposite each other, and
each has a rectangular, horizontally elongated shape. Each cover 25
has two horizontally oriented lateral faces 28 and 29, between
which a front face 30 extends from one vertical edge 31 to the
other edge 32. The front face 30 has an outwardly directed convex
curvature, which increases starting from the edge 31 shown on the
left side of the drawing to the right edge 32. The left edge 31 has
an angularly projecting lateral face 33. At the right edge 32, the
front face 30 tapers to an apex due to the greater curvature, so
that a direct glass support is formed there. In the lateral edges
33 on the frame side, there are recesses 37 and 38, through which
the elements located in the functional inserts, e.g., in the form
of a latch and a locking bolt, can be passed horizontally. The
opposing fitting 24 installed in the side part follows in its shape
the lateral face 33 of the lock fitting 21 and tapers to the
surface of the side part. In this way, the whole fitting forms a
unit and has a uniform curvature of the entire front face 30.
[0065] A handle 58, which can be inserted in the functional insert
of a lock fitting 21, is shown in FIGS. 17 to 22.
[0066] The handle 58 consists essentially of a grip 59 and a
connecting element 60, which is installed as a single piece at one
end and produces the nonpositive locking connection to a swiveling
element (not shown), such as a door or its fitting. Both the grip
59 and the connecting element 60 have a round cross section. The
handles 58 are made of high-grade steel, bronze, brass, or some
other metal.
[0067] The embodiment shown in FIG. 17 is a set of two handles 58,
which can be mounted on both sides of a swiveling element. The
handles 58 are identical and can be mounted mirror-symmetrically to
each other. Each grip 59 is curved convexly and sloped inward along
its whole length. This results in a grip shape that corresponds to
the natural shape of the hand, so that an advantageous tactile
sense is assured. The grip 59 is designed without contours and has
a uniformly round cross section.
[0068] The free end 61 of the grip 59 is bounded by an inclined,
preferably flat end face 62, whose region near the swiveling
element is farther from the connecting element 60 than its region
farther from the swiveling element. The transitions between the end
face 62 and the grip 59 have either bevels or radii 63.
[0069] The grip 59 makes the angular transition into the connecting
element 60 as a single piece and at an angle of less than
90.degree.. This creates the inwardly directed slope of the grip
59. The connecting element 60 is unprofiled and has a round cross
section. The diameter D of the connecting element 60 preferably
increases, starting at the grip 59. A latch pin 64 is installed in
the connecting element 60 for connecting the handle 58 mechanically
with a locking mechanism and/or an opposing handle 58.
[0070] FIGS. 19 and 20 show a design of the fitting 21 as a center
fitting with a horizontal orientation, such that the fitting 21 is
preferably mounted in the middle on the swiveling side of a glass
element. In this case, the handle 58 of the invention is integrated
in the fitting and operates a latch by means of a locking mechanism
installed inside the fitting 21. The latch works together with the
corresponding holding fixtures of an opposing fitting (not shown)
installed in a side part. The fitting halves of the opposing
fitting produce an ergonomic unit in continuation of the curved
shape of the fitting halves 22 and 23.
[0071] The fitting 21 shown in FIGS. 21 and 22 differs from the
fitting 21 shown in FIGS. 19 and 20 only in that a lock can be
additionally inserted into a corresponding opening 40. By means of
the locking mechanism installed in the fitting 21, a key, which can
be inserted in the lock, operates a latch, which engages a
corresponding recess in the opposing fitting.
[0072] The basic design of a fitting 1 is described in greater
detail on the basis of FIGS. 23 to 25. The design of a lock fitting
21 differs from it only by the integration of a lock and/or a
handle. The fitting 1 consists of mirror-symmetrical fitting halves
2 and 3, each of which has a substructure 42 and a cover 4 mounted
on it. The substructure consists of a base 43 and a functional
insert 44.
[0073] As was described earlier, fittings 1 of this type are used
for the rigid or flexible connection of all-glass elements 45 in
all-glass units. The glass elements 45 have bores or openings to
allow mounting of the bases 43 on both sides, preferably by
clamping with screws, possibly with the intermediate insertion of a
glass protector. Functional inserts 44 are then mounted on these
bases 43. The functional inserts 44 may allow, for example,
flexible support or rigid mounting of a glass element 45. This
modular construction of the fitting system allows interchangeable
use of bases 43, functional inserts 44, and covers 4. The glass
elements may be designed, e.g., with specific colors or
profiles.
[0074] The base 43 has a flat and basically rectangular design,
and, on its upper longitudinal side 46 shown in FIG. 17, it has two
vertically inwardly directed blind holes 47, which are spaced some
distance apart and are narrowed towards the outside by a
constriction 48. Each blind hole 47 contains a spring 49, which
presses a stepped pin 50 against the constriction 48, so that the
pin 50 is captively positioned in the blind hole 47. When the
spring 49 is in its relaxed state, the pin 50 extends beyond the
surface of the longitudinal side 46. In the lower longitudinal side
51 shown in FIG. 17, the base 43 has two vertically inwardly
directed bores 52, which are spaced some distance apart. The bores
52 are axially aligned with the blind holes 47.
[0075] Each cover 4 has two horizontally oriented lateral faces 5
and 6, between which a front face 7 extends from one vertical edge
8 to an opposite vertical edge 9. The cover 4 has a rectangular
outer shape. The front face 7 has an outwardly directed convex
curvature, which increases starting from the edge 9 towards the
edge 8. The right edge 9 has an angularly projecting lateral face
10, which spans a vertical edge of the glass element 45. At the
edge 8, the front face 7 tapers to an apex due to the greater
curvature, so that a direct glass support is formed there. The
lateral face 5 is provided with a recess 14 at the edge of the
glass, through which the elements connecting the functional inserts
44, e.g., in the form of a bearing pin 53, are connected.
[0076] Between the front face 7, the lateral faces 5 and 6, and the
edges 8 and 9, a receiving chamber 54 is formed on the inside,
under which the base 43 completely disappears after assembly. The
lateral face 5 has two grooves 55 spaced some distance apart on the
inside. The lateral face 6 is penetrated by two openings 56 spaced
some distance apart.
[0077] Before the substructure 42 is mounted on the glass element
45, locking elements 57 in the form of grooved pins are driven into
the bores 52, so that they are frictionally engaged. In accordance
with an embodiment that is not shown in the drawings, the locking
elements 57 can be formed on the substructure 42 as a single piece
during manufacture. After the subsequent mounting of the
substructure 42, the lateral face 6 of the cover 4 is set obliquely
on the longitudinal side 51 of the base 43, so that the openings 56
are engaged with the locking elements 57 to provide positive
locking. In the subsequent tilting movement of the cover 4 in the
direction of the glass element 45, the receiving chamber 54 is
completely inverted over the substructure 42. During this
operation, the pins 50 are pushed back into their blind holes 47 by
the action of the springs. Under the action of the springs 49, when
the appropriate final alignment of the cover 4 is achieved, the
pins 50 are pressed into the corresponding grooves 55. In this
position, the cover 4 is fixed for the time being. The procedures
described above are carried out on both sides of the glass
element.
[0078] A possible disassembly is carried out in the reverse order.
In this case, the cover is pushed as far as possible in the
spring-relieving vertical direction, so that the grooves 55 and
pins 50 can then be disengaged under a slight tensile load by
swinging away the cover 4. On the lateral face 6, the connection
between the openings 56 and the locking elements 57 can then be
broken by simple vertical movement of the cover 4.
